Well, I'm hooked. It could almost be considered an addiction. From what I hear, it's "sweeping the nation". Every night before I go to bed, you could bet that at some point in time during the day, I've completed a Sudoku puzzle (pronounced "sue-dock-oo" with equal emphasis on each syllable).
Are you as into this as I am? Seriously. I have a computer program on my laptop, a book of puzzles that I go through and I hit up Web Sudoku at least 4-5 times a week.
For the unitiated, the rules are as follows:
In an 9x9 square grid, (made up of 9 3x3 grids or "regions"), simply fill each individual box with a numeral 1-9. You cannot replicate a number inside a row, column or component 3x3 region.
That's it. The puzzle comes with some boxes already filled in, you just do the rest. The less amount of given numbers, the harder the puzzle.
Here's an example:
For those not mathematically inclined, no worries. The puzzle requires no math outside of recognizing the difference between each single-digit number. It's more of a logic puzzle than anything else. If you're interested, check it out!
